Subject: * Fleshes more of NPCModule out. * Implements some OSSL commands:    
     key osNpcCreate(string user, string name, vector position, key
 cloneFrom);         void osNpcMoveTo(key npc, vector position);         void
 osNpcSay(key npc, string message);         void osNpcRemove(key npc); *
 Untested. Requires ThreatLevel.High.
